to when you go, yeah, i would never do that or couldn't do that because of the laws in my political jurisdiction or whatever, we are not allowed to do that. then there's going to be other things when you think, gosh, i never thought about that, i think that would work really good. i'm going to take it back it my jurisdiction. probably over the past few years i've got 500 people i've dealt with, officers that have come to the class and subsequently become gravanis experts and set up programs. almost every program is different. a lot of the basis is the same, the information is consistent worldwide but people will tweak what information they are going to use and how they are going to be allowed to operate. some are in plain cars, some in marked units, it all depends how it's going to go. take the information you get, there's so much good information here today and tomorrow, take the information you want, take it back and integrate it into however you are going to work your program. when we come right down to it, it's not important what you know, it's what you can prove in court.
